Wizard: I brought the wrong system.

Chapter 105 The Eight-Sided Mirror Method
Bosco looked at the sketch and nodded slightly, saying, "Not bad. Theoretically speaking, there is indeed a possibility of success."

"However, what is the principle behind the eight-faceted mirror method that you wrote below?"

Bosco read aloud the explanations on the scrap paper.

“Eight sides were fitted with mirrors, forming an octagonal column with mirrors facing outwards. The eight sides were named ‘1’ to ‘8’ respectively.”

"A reflective surface is placed at a distance. In order to ensure that the light can be fully reflected back, the outer layer of the reflective surface is curved and the inner surface is a straight mirror."

"First, shine the light source into the '1' mirror, and the observer stands behind the '3' mirror."

"Adjust the angle so that, when stationary, the observer can see the reflected light source."

All of the above are preliminary preparations. Once everything is ready, testing can begin.

"Start rotating the octagonal mirror."

"Because the angles had already been adjusted, when the angle of the octagonal mirror shifts slightly, the light source can no longer reach the '3 sides' through its original angle, and the observer cannot see the light."

"As long as the observer sees the light, the experiment is considered successful."

After Bosco finished reading, the wrinkles on his face almost pressed together, and he looked completely puzzled.

It's as if it's saying—Who am I, and what did I just see?
"Something doesn't seem right, does it?"

Bosco pointed to the scrap paper and asked, "Your light source isn't blocked, and there are mirrors on all eight sides. As long as the eight mirrors keep rotating, the light will always find the right angle to pass through, right?"

"You say this is an improvement on the gear method, but I think it's not even as good as the gear method."

If you don't understand it, you'll naturally think it's inferior to the gear method.

Yaro chuckled and asked, "Are you wondering why the light sources here aren't spaced out like in the gear method?"

"Also, why are all eight sides fitted with mirrors? Why not just 'one side' or 'three sides'?"

“Yes,” Bosco nodded.

Yaro asked, "Could you give me a small octagonal prism?"

Friendships are built through back-and-forth interactions.

One-sided efforts can only move oneself.

Only by involving Bosco in the matter to a certain extent can we make him more attentive to it.

“No problem,” Bosco did not refuse. He gently raised his hand, and the square, bright silver metal floated in the air.

An invisible pressure was generated in the space, and the edges of the metal quickly flattened, forming an octagonal prism about the thickness of a fist in the blink of an eye.

Bosco asked, "Is this big enough?"

Looking at the two-finger-thick 'steel bar' in the air, Yaro smiled wryly and said, "Could you flatten it a little more? The edges aren't sharp enough."

Bosco looked at the 'steel bar' in mid-air, and the invisible pressure reappeared. The 'steel bar' began to shrink, eventually forming a metal rhombus the size of a bowl.

"That's it!"

Yaro quickly shouted to stop, otherwise the metal would be compressed into a rhomboid octagonal sheet.

Bosco caught the falling metal piece with his wrinkled hands and handed it to Yaro.

As soon as Yaro took it, he discovered that the metal block was actually warm to the touch.

Is this because of the residual heat from being squeezed?

'No, this warmth seems to be flowing into my body!'

The slight pain in his right arm was lessening, and Yaro asked in surprise, "Lord Bosco, what kind of metal is this?"

“This is Holy Light Mithril, with an excellent luster,” Bosco glanced at Yaro’s injured right arm and added, “This energy can stimulate the recovery of injuries, but don’t hoard it in large quantities. Large amounts of Holy Light Mithril may attract the attention of powerful beings.” In just a moment, the warm current had weakened, and the small amount of Holy Light energy contained in the metal should have already merged into Yaro’s body.

Is this a perk for me?

Yaro picked up the octagonal prism, looked up at Bosco, and said, "Your two questions can actually be answered by understanding just one thing."

As he spoke, Yaro picked up the octagonal prism and casually pointed to one of its facets, saying, "Let's assume this is 'face 1,' and that's the direction from which the light enters."

“We only need to rotate it a little bit,” Yaro said, gesturing to rotate the octagonal prism. “If there’s even the slightest deviation, the light will be at a different angle and won’t reach the original angle.”

Bosco quickly pressed on, "Then when the next side comes, won't it be able to shine the light in again?"

“You’ve overlooked one thing: when it rotates, the angle at which the ‘3 faces’ receive the light also changes. The observer is no longer attached to the ‘octagonal prism’; the observer will be far away from the ‘octagonal prism’.”

“When the ‘octagonal prism’ is rotating, the angle of the ‘receiving face’ will be different from when it is stationary. If there is even a slight difference, the observer will not be able to see the light.”

Yarrow concluded, "Therefore, we do not need to space out the light sources."

Bosco frowned and said, "Then why not just cover 'side 1' and 'side 3'? Why cover all eight sides?"

Yaro picked up the octagonal prism, slightly rotated it, and then smiled at the old man.

Bosco's eyes crinkled together as he stared at the metal in Yaro's hand, his eyes narrowing slightly.

“One-eighth?” Bosco whispered uncertainly.

To put it simply: the octagonal prism in the middle rotates continuously, causing light to skip over one mirror and be reflected back along its original path by the mirror below the octagonal mirror.

Yaro nodded with a smile, praising sincerely, "Lord Bosco, you really understand everything at a glance!"

That's truly lying against one's conscience!
“You’re making fun of me,” Bosco quickly waved his hand. “I can’t keep up with your train of thought at all. You’ve written down all the answers and put them right here.”

"They even pinched and crushed it bit by bit, but after watching and listening, I still felt like I only vaguely understood it."

"I feel like I understand everything, but I still have a lot of questions."

"Looking at these solutions again, they all seem to make sense."

"Your thinking is brilliant."

Bosco shook his head slightly and sighed in admiration, "I can't even understand the plan you wrote. I really don't know how you came up with this plan out of thin air."

Even though others wrote it down clearly and explained the whole process step by step, Bosco still didn't fully understand.

Such a huge gap left Bosco completely convinced.

"I'm really getting old!"

"You are a true genius, and geniuses deserve more preferential treatment!"

Bosco sincerely asked, "I am willing to accept your proposal on behalf of the Academy with three thousand contribution points."

Since Yaro has already presented these solutions, he naturally won't refuse.

"Thank you for the gift from the college."

Bosco asked earnestly, "Are you willing to actually carry out these experiments?"

Yaro nodded: "Of course."

“Then…” Bosco hesitated for a moment, “could I work as an assistant?”

"Don't worry, once the results are out, your contribution points will be fully credited. I just hope... that my name will be listed in the corner of the signature section."
